Abstract: | In the present investigation, we have made first shot to propose an alternative estimator of population total, in the presence
of random non-response, for multi-characteristics by using probability proportional to size and without replacement (PPSWOR)
sampling when the selection probabilities are poorly correlated with the study variables. The mean square error (MSE) expressions
are derived for the proposed estimator. The behavior of the proposed estimator has been examined under super population model.
An empirical study has also been carried out to look into the performance of the proposed estimator. The proposed estimator
has been applied to real data set. |
